What you'll do

A watchdog on your router's power that Claude Code built with you — an ESP32 that probes both your own router and two independent points on the internet every thirty seconds, waits out a five-minute patience window before it believes anything is really wrong, then interrupts only the low-voltage output of the router's plug-in brick for twenty seconds through a relay wired so that power flows whenever the watchdog is de-energized, dead, or unplugged — and that then refuses to try again for an hour, refuses to try more than three times a day, remembers those attempts across its own reboots, and latches into a visible give-up state instead of power-cycling your house all night.
